Need help to get to Nature Sanctuary?

Question

I am working on getting complete regional pokedex in Black 2 so I can go to the nature sanctuary. Im stuck with a few Pokemon but the only one I need help with is reshiram. so is there any way to get its pokedex without trading or BUYING white 2?

Answer 1

You could hack.thats my option but other than that those are the only ways.

I would but I choose not to mainly because I don't want me 3Ds to explode.... Exaggeration...
